I feel that all will be well with the versatile alternatives you will now have.
My two "daisy chained" kits of four work really well, swapping between the supplied "rubber duckies" and four "original" v.1 P180 paddles. With a bit of attention to "aiming" my P180's, I've had stable outdoor, line-of-sight, "real world" reception from a sweaty rugby referee's TBP12 belt-pack 300 metres away, more than triple Line 6's specification !
Line 6 never seem to rest as far as improving their products, so I suspect v.2 addresses production niggles that are "invisible" to most of us, ...maybe things like DC current drain, internal solidity, revised componentry or some such.
Your choices are now great, in that you could "mix and match", based on a pre-performance "walk test".
For example, there'd be nothing stopping you from running one "side" nearby as "omni", (rubber whip or P360) located "inside" the perfomance space, with the more distant other being an aimed P180 that "sees" the same "arena" around RF obstructions, with coverage from a totally different angle.
Incidentally, although a BNC "video barrel" joiner between two lengths of LMR-195 will definitely "cost" some signal, there may well be locations that work better with a more distant angle being achieved like this, with the loss from the joiner being compensated by more gain being switched in at the paddle's "head" amplifier.
As ever, a "walk test", coupled with the XD-V receivers' excellent front-panel diagnostics, will quickly yield a "safe" solution for any location, no matter how "strange".
