Just got home from the RED SEA last week. We originally planned to stay in the Sharm area, but we changed plans and went to Brothers as well.. I'm very glad we did.
Lots more to see, lots of sharks in particular. Both longimanus and thresher and lots of reefsharks(I lost count)
See this link.. we had a very nice encounter with a Longimanus at 30 meters.

About the wetsuit, well it was just perfect.
The water was between 23-25 Celcius. I was also wearing a 1mm torsoe rashguard under it and a 3mm hood. I don't know if that made any difference. But the suit was very fine even below 30 meters. The dives were not very long, only between 40 min and 1 hour.
However I believe that any colder than 21-23 C, this suit will be a little too cold for long and deep dives.
The best thing about the suit was putting on and taking off the wetsuit. While the others were struggeling with their 7mm semi-dry, I was in and out of mine in less than 30 sec. VERY easy to put on. I might add that I have the Deluxe version of the Trilastic.
Vanessar you asked what Liveaboard I used.
The boat I was on was named Golden Dolphin II(I belive that was the name of the company as well, see their website).

I can higly recommed this company. Very competent guides(two of them), nice food onboard and free Nitrox. I have only positive things to say about the tour..
Best regard
