Default Titanium Screws in Alum for Offroad

I hear that Titanium Screws into Aluminum tend to bind.
I have heard people using a tiny amount of grease or threadlock.
The grease I understand, but if your having problems with the screws binding to the aluminum, wouldn't the threadlock make it worse?
Or, does it create a barrior between the two that doesn't allow it to bind?

I'm finally going to replace my 501X screws which have been sitting around forever.

I can't say I noticed it bud. I have replaced all the (nasty) screws on my 501X with cheap Ti screws, the heads are so much better than the kit ones anyway that there have been no problems.

Thread lock actually works just like grease for this purpose, just not slippery. It insulates between the two types of metal and seals out ant contaminants. Use locktite blue and you will be able to get these screws out down the road. If you don't you will experience titanium "galling" where a tiny bit of bionic corrosion forms and the two pieces of metal will be together forever. This was a common problem with Titanium bicycles. Water bottle screws, bottom bracket threads and seat posts would all get stuck, usually permanently. This all ended when we began using anti sieze compound.

I've run ty screws in my last 3 Mugens with no issues. The only place I don't use them is on the chassis braces because they tend to break there. Ty screws can save you a whole lot of weight if you use enough of them but they are more brittle. My rule is to replace as many srews as you can with ty then if one breaks put a steel one back in that (strees prone) location. The only problem I ever had with "galling" was strangly on the ty hinge pins in the A-arms (plastic). I'm still not sure I understand why that happened (every time).
