I'm not a fan of Snowpeak either, largely because I feel like it's a dungeon heavy on backtracking and very weak progression. However, the dungeon I'd cut from Twilight is the Sky Temple. I just can't stand its shitty music and tedious progression, not to mention the lame Double Clawshot dungeon item (which pretty much does what the normal Clawshit should have done from the beginning).
Honestly, my complaints with Snowpeak kind of sum up Twilight Princess in general: it takes for-****ing-EVER to do anything substantial or get anywhere because you have to go through every area twice, often bogged down with lengthy, boring, silent cutscenes. You even have to run through the Lost Woods twice for no apparent reason. It's loaded with so much sheer padding that the entire game feels about 30 hours too long for me. Sadly, Nintendo didn't learn from any of their mistakes in TP and just made them even worse in Skyward Sword.
