Big problem?

Hi everybody!
Seen a nice glass board on ebay its 7.2' long 20 7/8" wide 23/4" thick.
Im about 6' tall weighin 13.5 stone, and would be surfin mostly in 2-3ft west wales waves.
Im currently ridin a bic 7'6" (cts construction) performer which doesnt catch everything but is fairly floaty.
Would this board be a wise investment?
Ive only been surfing for over a month but i can sort of go left and can ride about 60% of what im catching!!!!!!!!!!!!
Please help!!!!!!!!111
