I"m gonna go with:
Go out - and shoot the marker for 2 months. No changes.
When you finally finally FINALLY get a feel for the marker after 6-10 cases, think about making changes to it.
There's this common thought that any upgrade out there for anything is better than what you already have. There's also this thought that you absolutely need to upgrade a marker to make it shoot smoother/nicer/better.
The truth here - is that most aftermarket preached upgrades run 20-50% of the marker's retail value, only minorly boost efficiency, and you'll find out... do nothing but remove money from your paint budget.
It used to be true that upgrades could overhaul or massively change the inner workings of a marker. Those that balled back in the early 2000's (and possibly prior, can't speak on that) remember how you could put $100 into a few upgraded parts on a marker, and you'd see night and day difference. Replacing a stainless steel bolt with a delrin one? Awesome...etc. Now, manufacturers have gotten much better at making a finished product.
Taking a current, common example -
TechT bolts for ETEK3/4:
They're $44, which is about 10% the cost of an LT. They improve efficiency...but is that needed? I pushed 8-9 pods through my ETEK3 this last weekend on a hot-fill 68/45 without glancing at the gauge. I wasn't out of air.
TL;DR - Go out and shoot your marker. Then put 5 more cases through it. Then...and only then.. look into upgrades. You may be trying to fix something that isn't broke.
