I'm getting tired of this................and will change my previous answer....to convert to a nose gear..
Other than that, it's again being practical. The "other" thread relating tailwheel accidents due to lack of visibility is a good example.
I personally know two pilots who ended up cramming a Pitts S2B into a aircraft towing tractor because the tractor ran out of gas at the wrong time, with a blinding setting sun behind it. This aided in my decision to finally go with the nosewheel, where visability is improved.
Now, other than that, RV8's must be taildraggers for WWII markings. It's the only reason I can thing of..
Apparently RV taildraggers are not that hard to fly, so the RV TD pilots aren't really macho enough!

They don't behave badly enough, and are easier to see over the nose..
And lastly, REAL taildraggers are meant for bush type flying along with tundra tires. This is where taildraggers are truely practical. If you don't dare take your RV into those type of conditions, then get a REAL taildragger!...
