My lefty Hallmark Custom 60 in Sunset Sparkle finally arrived this AM. I'm new to these (seriously - have you ever run across a lefty Mosrite? Me either

I'm still feeling out this guitar after a few hours playing it. The fretboard radius is a little flatter than I'm used to and the action is a lot lower. I'm going to leave it as is for now and see what happens as it settles in, but I'm really wanting to jack it up a little and see if bending is more precise for me.
The pickups are weird - high output, but low on sustain. Like a P-90 banged a Jazzmaster while a FilterTron watched type sound. I can get LP Junior-ish sounds on the bridge, then flick to the middle and its practically a Gretsch. The neck is bassy but fairly clear sounding. Really screwing with my head as they are so different from anything I've had previous.
The Vibrato is great! In the 35 years I've been playing I've never owned a guitar with a wang bar on it and this one is very smooth - easier than a Bigsby and a little more responsive than a Jazzmaster. The bar kinda gets in my way sometimes but I'll adjust. The one thing I'd like to do with it though is to put some sort of washer between the arm and the rocker - I'm feeling metal on metal and its a tad loose. I'd like to be able to let it swing away a little easier if I could but I don't want to introduce any rattle. I'm thinking a very slim silicone washer might do it? What do you think?
Pics on another day - the light is really crappy here in rainy/snowy mix Oregon and I want sunshine to show off this fricking insane flake. It's a beautiful guitar!
