I play the forward tee at my club at 5900yd/73.3/140. My husband usually plays the regular tees at 6900yd/72.2/142. He played the forward tees a few times and he did not find it any easier nor did he magically shave off strokes to break 80 (he is normally in the mid/high 80s). He was disappointed because he expected a shorter course to be easier but it required him to use clubs that he normally wouldn’t use and he got into hazards that normally weren’t in play. Eventhough he was playing the same course, teeing forward was a completely different game for him.
I have played at my previous club a few times - forward tee was 5100yd/68.4/127. I expected to play better but didn’t for the same reasons as my husband.
I birdied 14,16 & 17 coming down the stretch today at TPC Myrtle Beach to finish with 74 from the tips and that course is literally one of the most difficult and extremely long especially with recent rain.
