I think inzer is overrated... The fact that they still sell their old outdated shit for full price and anything that says "inzer" on it costs double pisses me off... They know theyre the biggest name in power gear... Ive only ever competed in an Apex shirt (I have two) and they are incredible... For other gear, I only use titan anymore- Ive used 3 different squat and dead suits and they work awesome for the price. (Titan actually has sales and moves old product at a discount!) I finally picked up a titan 2 ply shirt and was very impressed- it fits right between my two apex shirts (around 500 with the single ply, hit 565 with the triple) for those feds that have a 2 ply limit... I have yet to use it though, but like everything Ive got from titan, fit was excellent....
As far as other gear, I use almost exclusively apt- belt, wrist wraps, knee wraps... Solid gear and Alan from APT bends over backwards for his customers...
For denim I dont know, much of the newest poly works at almost the same level... A buddy of mine (national champ bencher) uses a metal denim and its ridiculous what he gets out of it... 700+!!!
