Help sizing up a Lost RV/Groveler!! 5'10 vs. 6'0

Hey all, I come seeking your advice! I have my mind set on the Lost RV and am having some trouble deciding between sizes. A little background on me:
I am 6'2'' around 185lbs. In my mid 20's and in decent shape. Been surfing for 6-8 months and have picked it up relatively quick (skate/snowboard background). Started on a 6'8'' hybrid, then about 2 months ago purchased a 6' Rusty Dozer. Roughly 32L of volume. It's been fine for the most part and I've had a lot of fun on it but I am missing more waves than I'm catching in less than perfect conditions. (surfing mostly beach breaks in So Cal). I tend to get left at the tops of waves and let some good rides just pass underneath me. I am trying to change that and want to step up to a board with more volume to up my wave count.
That's where the Lost RV comes in. So I am stuck between two available sizes.
5’10″ x 21.75 x 2.56″ | 37.52L VOLUME
6’0″ x 22.25″ x 2.75″ | 42.18L VOLUME
A 5'11'' would probably be perfect but non of my local shops have one and I don't want to spend another $100 for shipping...
Both are a decent step up in volume. I am wondering if it is better to go for less foam or more foam? Surf should be picking up now that it's almost winter and my surfing is only going to improve so I'm starting to lean towards the 5'10''. It is still an increase of about 5 litres of volume from my last board and I like the idea of something shorter/skatier that I can whip around. But at the same time I just want to catch more waves!
Any thoughts would be greatly appreciated! And if you have any questions for me that might help in the process ask away!
