I ride The Nick on a compact double with 34/27; I'm 58 and I weight just over 11 stone or 72 kilos so I guess that in comparison with some other amateur riders I find climbing easy! It's a long boring climb but manageable with those gears, standing up part of the way. However if you wanted to spin easily up it in a relaxed way you'd do better with a triple, yes. How fit are you and what weight?
Even the north side of Jeffrey Hill is doable with a compact double but not with much style! Some folk will tackle Rawson's Raike in Ramsbottom on a compact double but I've only ever ridden that one on a mountain bike with something ridiculous like a 24/32, which just becomes an exercise in cardiovascular stamina..
