well i never had split toes so I cant say if I woudl like them or not. 5 finger gloves just bother me . It make my hands feel all swollen like someone bashed them with a hammer and there all puffy
less seams, plus it keeps three of your fingers together for more warmth. having the index and thumb separate is enough maneuverability for me to grab the board, duck dive etc...
I go 5 fingers for a 3mm
As for the boots, some days I've found myself wanting 7mm in OCMD
I prefer mits over gloves . I cant weat 5 mil gloves plus with mits your hands will be warmer cause most of you fingers are closer together. For boots I use 7 mils cause I hate when my feet get cold once that does I am done for the day
i operate off of this principle as well...& in the dead of winter, that means 5mil roundtoe boots w/ a pair of socks underneath (makes the boots a TON warmer! try it!), & either 3mil or 5mil 5 finger gloves. i like to have as much dexterity as i can (which precludes mitts or claws, IMO) & have found that if i can wiggle my fingers, they will stay quite a bit warmer. which i wear on which day depends on the wind & air temp. i wore the 5mils A LOT last winter.
i'm also one of those guys who tries to wear a 4/3 thru the entire winter. generally i succeed, except on the absolute coldest of days (& last winter).
