Rock sliders

If I were to get rock sliders for my Taco, which is better: bolt-on, or weld-on? I've been thinking bolt-on would be better, as you can remove and repair them easily, but they seem to be more expensive. I also don't know how drilling holes in my frame would affect its strength.

Any thoughts on the subject?

I made mine bolt on and drilled through the frame. I did that so I could remove them when I wanted as well as re-painting them. Check on TX-TTORA, I think Grady (Whackmaster) was selling the ones I built not too long ago. He's in Huntsville.
