The only differences of note between the two, imo, is balance and precision..
Nike has more precision, but go deeper than the 20 scale and this tells. A deep meter with the nike will have an appreciably larger grouping 25 feet away than the Versa would.
Versa more balance, and so you can use easily use that 50 foot (shorter travel back) scale more. Yes less precision technically, but especially using the 15" scale (and heck spot the difference with the 50 if can every month) I don't see you would notice score wise v often.
Choices but no rush, and so waiting for a free rental would be wise IMO - v rich from me being a sucker in the toy shop, lol.
Now If they ever brought out a L94 Nike with an extra dot of balance or even better a L96 Versa with .5 slower meter. Then again not sure the game really wants that...
