I hope you don't give up Dricketts. I agree with the same sentiment everyone else has shared about your route. I remember seeing it years ago and being impressed with what you had.
As for TANE, I wouldn't sell it short just yet. I only imported my route into it to see what would happen.... Posted pics as much as a gag as anything else.... Then I had a couple gentleman offer to help me get things sorted out, so I started looking into what was actually broken and what wasn't... In the process I got to play with some of the newer features and see what its capable of..... I've been really impressed so far just with what has been released.... Yes, it sucks that not all content won't port directly into it with no problems, but I'm already talking to people about fixing much of what breaks, and alot of it seems pretty easy fixes. The only hard one to fix right now that I'm encountering as a migrating Route Creator is Trees, and we already have two of this hobby's greatest Tree makers working to fix that, one of which has already released (As payware) working TANE Speed Trees....
Anyway, if we all dig a hole for ourselves and never share anything again, what was the point in getting into this hobby in the first place? I know I'd like to see your route completed, as does I think about everyone else here. At the end of the day if you complete it in TS2010 and never share it beyond pics, awesome. If you share it with the community in TS2010 outstanding. Point I'm trying to make is, I for one really hope you don't let a little thing like a program revision you don't have to partake in stop you from completing a route that has been so obviously central to your interests for so long and you've made such wonderful progress on.....
But whatever you decide, I will respect your decision as the route's creator,
