clutch advice please

I'm looking at buying a stage 2 clutch for my 01 tibby but not sure what one to buy. I'm looking at the unorthodox racing ultra g kevlar clutch kit (http://www.sportcompactonly.com/product.aspx?p=100107&c=83&l=2) but I have no idea what the diference between rigid and sprung hub is or windowed and full face. if anyone could tell me which would be best or if there is a better and/or cheaper alternative please let me know

Hmmm the only part of your post i can answer is about finding a cheaper alternative, i wouldnt try to because you want to get the highest quality clutch you can, soo 400 isnt bad at all if your getting a great clutch compared to a 100 dollar POS

Why, is your clutch going out?
