I'm pretty much the same as you. I don't gig, or record, and I bought the LT. Some may say it's overkill, but if you can afford, do it. You will be really happy. You don't necessarily need the full helix in your situation, the LT would be more than enough. At the end of the day, I had spent more on an EVH 5150 amp, a couple pedals and a two notes torpedo CAB to get 1 really good sound, versus the plethora of options I now have with the helix.
FRFR is great, but if bedroom playing is the only thing you're doing, a decent set of headphones will do the trick until you can pick up an FRFR speaker.
