My choices came from reading literally hundreds of post on various message boards and what opinions lifters have had from using the different suits.. So I narrowed it down to what seemed to be the best available.. From what I've seen the Hardcore is one of the most highly praised suits and seems to be the best choice for a combo Squat and Deadlift Suit, plus it is legal in all federations... My choice of the Ginney Phillips Custom Canvas suit came from a recomendation I got from Dave Tate over the Phone...I spoke with him when I called Elitefitnesssystems to change a shipping addy for a video I ordered.... I just happened to work in what suit he would recommend, and he said that hands down the Phillips is the best around, even better than the Frantz that Westside primarily has used... And for a all fed legal suit he recommended the Hardcore also... My choice for the Boss came from the immense rave reviews I've seen for the Titan suits.. And supposidly the BOSS blows their other suits away performance wise... As far as deadlift suits, the same applies here...Although I would simply lift in the Hardcore if I went with it, I would need a separate suit for deadlift if I went with one of the canvas...And the two I listed seemed to have the greatest following...Of course another option would be to get a Canvas and the Hardcore and then I would have to the Hardcore to deadlift in and squat in in Poly or single ply only Feds...Grrrrrr, so many choices....But I have at least decided on Frantz Power briefs, lol I think.......
