These are the specs to my current chair. I'm wondering if anybody has any suggestions. I'm thinking about a Tilite TX. If I go from a 5 " caster to a 4", change the front end from 80 degrees to 85 and change the back seat height from 15"to 14", can somebody tell me the advantages and disadvantages? Also, by looking at the specs, can you tell what my dump is and should I tweek that as well?
