I'd suggest you try wearing the suit for a bit before you make any
adjustments to the seals. If you really do find them intolerable, then
stretch cautiously (you can always stretch them further, but you cannot
"unstretch" them). You're trying to hit the balance that allows you to wear
the suit comfortably, but still provides an effective seal.

I would not recommend cutting seals, for two reasons:

1. You are trimming away part of the "taper" that seals against your skin.
The greater the area that seals against your skin, the more effective the
seal.

2. More importantly, any unevenness and or notch in the cut can act as a
"stress riser". The seal is a "tensioned structure" in use, and stress
risers can cause the seal to split very easily.

As far as I know, all drysuit manufacturers suggest stretching rather than
cutting.

Happy, safe paddling,
