So would you rather choose being cold so you can move around more ? That is the dilemma you are facing warmth vs. flexibility. I have always been one wetsuit level above everyone else in the water here in Japan since I'm from Hawaii. When others are in 3/2mm, I'm still in my 4/3mm. And how much "restrictive" are we talking about ? Are you worried about the paddling restrictiveness or when you go to do a full wrapping round house cutback restrictiveness ?

"Ok" is general broad relative description. Is the Food served OK ? Is the clothes brand OK ? What is okay for someone may not be okay for others. If you plan to surf for only 1 hour, I don't think you need to worry about being restrictive. The thing you need to know is the more you spend, the better the flexibility is ( but sometimes not the longevity ) in wetsuits.
That said, the most "restrictive" thing is when your joints are stiff from being too cold. Go warmer.
