Im looking to get a new winter wetsuit but Im unsure what to get Im thinking the O'neill Mutient anybody have any recommendations.

The search engine is your friend. Theirs loads about suits on here, winter / summer....
We'll only end up going over the same stuff we discuss again and again and again

30 pages here

I thought the conclusion of the discussion was that we use a combination of lard, clingfilm, and then marmite as the last layer (for modesty reasons).

Got it in one, tight as a drum

and a pair of speedos underneath of you'd surley fookin die!!!!

West coat surf shop in wales are selling Ripcurl E-bombs for 150 sterling. Good suit for this time of year.Good value on sterling at the moment also. Ive seen some irish shops charge double that amount.

can't say enough about the ebomb (except for the zip - but I got that promptly repaired for free)
buy the rip curl hood which snaps on to the bat wing and you're in business.
