Huntersmurf and I have something in common.
My 917v is a great shooter as well...sub MOA with 17 grainers, and about 1-1.25" with 20's...surprising it shoots both so well.
I too did the the spring trick, and a polish job. Not super light, but great for a multi-purpose field/target rifle...mine sits at a crisp 3.5-3.7lbs...
The riflebasix trigger is sweet (yes, I've tried it on a friends rifle) but I prefer something a bit heavier around the farm and I still shoot well enough with a heavier trigger.
I say GO FOR IT on all accounts. The marlins are just a touch better than the savages, IMHO...though the accutriger is nice.
