Need help selecting new RF lenses vs my existing EF lenses

[SteveBouck]

I have an EOS R6 Mark II body that I recently purchased and am considering replacing my existing lenses. My primary interest is Landscape photography and Wildlife Photography.  My current lenses are as follows:

• EF-S 10-22mm F4
• EF-28-135MM
• EF-RF Lens Adaptor with Filter Slot

Questions:
1. Is there a big enough difference in the RF lenses to justify the high upgrade cost?
2. From a Wide Angle perspective, would I be better off buying a used EF11-24mm F4 or is there a big enough advantage that I should buy the RF10-22mm F4?
3. I love my EF28-135mm lense because ithe range covers so much of what I shoot. When I look at RF, all I really see is RF24-105, then RF70-200, and RF100-500mm. I don't want to carry 4 lenses to cover the entire spectrum, so what lense combinations would you recommend to replace the EF28-135 most and why?

I've thought about the following combinations:

1. EF 11-24mm F4, RF24-105mm and RF100-500mm
2. EF 11-24mm F4, RF70-200mm and RF100-500mm but would I have to low a gap on the low end?
3. Skip the Ultra Wide angle, and go with RF24-105mm and RF100-500 mm.

As you can see, I am frustrated trying to figure out the best combination for my outdoor photography. Any suggestons are much appreciated.

thanks,

Steve

"I think you mean the lens"

OK, however you word it the center is the best part so the OP could well be satisfied with it.
