My2Dogs

I started using the Iomic 2.1’s but for the price point tried No1 Series 50.  Absolutely love them but they are had to get and many don’t carry them.  Also they are expensive and I’ve seen over the past year they seem to be wearing out quicker than previous models.  Don’t know if it was a bad batch or maybe they have gone with cheaper materials to save costs?  Either way, with the price point I just saw the Best Grip Microperf and also made in the USA.  Also was looking at The Grip Master grips.  I’ve been playing more in the summer and work days have gotten longer and longer, even when starting at 6am.  So my rounds have been starting later and later and it’s hotter.  My hands have been sweating more and that also could be the reason for more wear on the No1 Series 50.  But it’s got me looking into these 2 brands for their leather grips that help when they get wet.  I use gloves but go through them like crazy.  I bring 4 or 5 when I’m having a practice session hitting 150 range balls and these grips seems like they could really help.  My hands wouldn’t slip as much and I’ve heard they last a long time.  Will certainly take a look as I will need to regrip my entire bag and backup bags soon.  

Bestgrips.com for me.
Leather grips with a tacky feel. I've never had a better grip when it rains or when the humidity gets so high and I sweat through every pore in my body.  I don't wear a glove and these grips are the best I've ever tried.  I have the mid size on my driver and 3-wood and the regulars with 3 additional wraps of double-sided tape on my irons.  2 years and they're still tacky. I wipe them down after every range session or round.  I will admit that they are expensive, but I expect they'll end up going at lease 3 years for me...and maybe 5.

After reading about them many times over a couple years, I finally took the plunge and tried leather grips.  I bought a couple Best Grips MIcroperfs and a couple GripMaster Roos and put them on a couple clubs.
They are the Real Deal.
They're tacky when moisture enters the equation, even if it's just the humidity in the air.  My grip on the club is ultra secure.  We get pretty humid up here in summer, with 10,000+ lakes around, I've had zero trouble with the leather in play.  I've put them on every club in my bag now.  
I ultimately chose the Roo grip (kangaroo leather), but also installed Kidd grips on another set, and a couple Master Perforated grips on the odd club.  All have been completely awesome.  They have varying levels of tack to them, but once the humidity kicks in, or there's a bit of moisture present, they're on the job.  I used to worry about taking a drink of liquid in the summer, from the condensation on the bottles, it's 0% on my mind, now.  
Leather grips are pricey, but they last a long time.  Cost ratio definitely on the plus side.
I count them as definitely worth a look.  
Side note:  I use an air compressor to install my grips, so I can remove them if I decide it's time to sell a club, or even just quit using it.  Just pop the grip off the club, move it to another.
