I have a PM7 and I'm trying to decide if I want to upgrade to the UL or just an aftermarket trigger. I tried searching for this info online and on the forum but didn't come up with anything.

The UL Frame vs a Normal trigger upgrade.
Does the UL frame have a better board then the stock PM7? Is the only difference the size / weight / trigger / grip?

Upgrading the board just adds more modes? Does it improve performance at all? I only play in semi auto mode so any burst or ramp doesn't make a difference.

Any other upgrades you guys recommend? I'm not a hardcore player but I'd like to improve the performance of my gun.

Thanks in advance.
