I can try, but a lot of it has to do with the fact that it is just the longest sustained stretch that doesn't really have any thrilling or standout holes or shots for me.
#7 feels like a really long, land eater transition par 4 to get up the hill. I get that you like uphill holes and really enjoy it. I don't have a particular problem with uphill holes. This one just doesn't have much allure for me. Very wide, very long, very uphill. Its fine, but it just isn't all that memorable for me.
#8 is always a disappointment for me. The iron or hybrid off the tee feels like a ho hum play to me but I don't really gain enough advantage or face enough risk for the driver to feel as exhilarating as I might prefer on a short par 4. It doesn't match up to some of the short par 4s I love at the resort, like #6 at Pacific, #14 at Trails.
#9 just seems like another long connecting par 5, although they did incorporate that nice pine tree into the back of the bunker. This hole is one of the most visually bland on the course to me. I actually enjoyed it more the last time I visited than the previous times around, and it is probably closer to the top of my list in this stretch.
#10 I'm probably guilty of I have no idea what this hole is even about because I'm pretty sure I always just bamboozle myself off the tee. I always have to go back and look at pictures to remember what's going on here. It looks nice and it photographs well, but at the end of the day it doesn't have a memorability factor for me. I have probably given this one less of a chance than the others in this stretch but it is right in the middle of the stretch I love to ignore, so it gets lumped in with the others.
#11 I think I would like this one more in the winter when I could challenge the hill, so guilty as charged on your comments about short hitters. In the summer wind, I really have no prayer of riding down to the lower tier. So, the tee shot is rather pedestrian. Just hit it out there and then face your super long approach to a ginormous green. I am actually quite fond of the green setting and how it nestles right up to the pond. It's peaceful back here, I will grant you that.
#12 I really like the giant knob on the right side of the green. But it really only complicates things when you miss way right. And I'm not going to step up to the tee and miss way right on purpose every time so I can enjoy the big hump. Otherwise for me it is just play the driver right up to the green and hope for the best roll.
I may be one of the guys you thrust into the "don't like it because I'm a shorter hitter and the course is hard" category but I don't know how you define that bucket. I hit the ball far enough to get around the resort - probably 230 to 240 on most of my trips out there (with the occasional 210 or 290 thrown in depending upon the wind!) So, I'm not super short but certainly closer to short than long by today's standards. It isn't the sheer difficulty of the course that turns me off, though I do agree it is harder than the other three. I'm not even sure that I agree with your comment about there being more unreachable holes at Trails than the other courses. I've never thought of 4 or 12 as unreachable and 11 is only unreachable in a really strong wind. Not to mention that I'm not really one to get hung up on not being able to reach a green in regulation (I love #15 at Kingsley and I have never reached the green in regulation in my 25+ rounds). I think there are holes that in certain winds are unreachable for me at all the courses. Trails just doesn't give me the juice the others courses offer.
