Well I took the plunge (pun not intended) and bought a floatation suit and from the advice I got (and the description of the pockets and how yummy warm they are) I decided to get the Sundrige En-Tec 2 pc. Checked all the measurements, chest, waist etc and it would appear to about correct with alittle extra room for my ribbed muscles (I wish).
Should receive it tomorrow and hopefully I won't have to send it back (winces).
Thanks for all the help guys, as always your experience counts a great deal.
