Trading Connections merged with On Screen Trading who were part owned by the Kyte group, so TC now clear through Kyte.
Don't know much about working direct at Kyte, I never heard anything bad about them and know a couple of guys who work there who dont seem to have any issues.
All depends on the deal really.
One of the T2W members used to work there (Traderboi), he wouldn't mind if you sent him a PM for some advice.
