Yes, 6 and 11 are monsters but #4 is very short and requires precision to put the ball on the correct area of the green or 2-putts are really a huge chore. 6 and 11 are uphill but 17 is downhill. It called variety requiring different skills.
#,s 7 and 8 are back to back challenging 4 pars under 400 yards but 2 and 5 are brutes over 450 yards. Variety that requires short irons, good driving, long irons and woods. Then when your get to the greens you had better have a deft putting touch and short game. That's just the front 9. It gets better on the back. Look at Ran's course profile. If this is your idea of a "little fun course", I'm really looking forward to seeing how far you go in the US Am later this month !
On a side note, the restoration done by Gil Hanse and crew is a model for true and ARTISTIC work. It contrasts with the work done down the street at Quaker Ridge, a compirable Tillinghast gem, which is serviceable but obvious where the new bunkers were built and the original "tillinghast style bunkers" remain. Fenway's work is so much better and in fact the bunkers are harder at Fenway as are the greens as are the decisions and execution required to hit the greens.
