ok...

I know two systems:
Switch grip
and
Grip Loc

now Switch grip made its way to Germany and there are at least three proshops I know using switch grip..

Any experiences with Grip Loc here? and what is that with switch grip?

Am "fighting" to get a good feeling in the thumbhole ... I have one ball which is perfect... the rest is giving me headache

You have two options for getting the same feel from ball to ball.  One is interchangeable thumb inserts.  The other is getting a slug made from a mold of the thumbhole that does feel good.  The reason I use interchangeable thumbs is because my thumb changes sizes pretty drastically depending on the time of day, so it's much easier and more consistent than adding and removing large quantities of tape all the time.  I can have a looser thumbhole for mornings and a tighter thumbhole for nights.

I'm not familiar with Grip Loc, but I used to have Switch Grips.  They were pretty good, but I had issues with some outer sleeves being much tighter than others (making it nearly impossible to get the insert out of the ball sometimes) and had a couple break on me.

I recently started installing Vise's new IT interchangeable thumb, but have only had them for about a week now and my ball driller and I are just now perfecting the installation process.  (We had to lower his drill press slightly to accomodate the hole for the molly that gets inserted deep in the ball at the base of the thumb inserts)  The system is very well-engineered though.  They put a lot of thought into how to do it best.  As I mentioned before, I'm going to post some pics of this when I get a chance.  (Been too busy the past few days!)

And yes, it's a pain to switch thumb inserts regularly -- I do NOT use an interchangeable thumb on my spare ball.  I'm not as worried about the feel on it being perfect, so that's fine for me.

I've used Grip Loc and have no complaints. It's very easy to install, and you don't need a 1 1/2" bit like you do with Turbo's Switch Grip.

I put 70-100 Grip Loc Thumbs in balls at the booth in ABQ,NM.

A really good product and very easy to install. Our demo ball had to be changed out between 700-1000 times and it still "clicked" in solid and snug.

It really is a great product.
I have heard all the horror stories about the Switch Grips breaking and hurting people. I chose not to ever even try it in my shop because of that reason.

Just a quick update, I now have the Vise IT thumbs in all of my equipment (except the spare ball, of course).  Now that we've figured out how deep to drill holes, etc., it's very quick and easy to install, and the repeatability is great.  Every ball feels the same on the thumb.  Almost no variance in height or pitch or anything.  It uses a much smaller hole than the Turbo Switch Grips since it's basically a standard thumb slug with a screw-in base (with a molly at the bottom for extra strength and durability) and a thin plastic ring in the top part of the thumbhole.  I've got all the pics now and should be able to post more info on these tonight.  But so far I love them.
