I'm a Gilmour nut.... And tend to get a bit anal about his effects etc so please forgive me. If you're doing Floyd you'll be wanting to split the delay time between the 2 cabs.
Gilmour regularly has different delay times for each cab/amp. For example in Run Like Helll He'll have 450ms in one cab, and in the other he has 600ms. You need to "fake" having 2 delays like he did back in the day.
The TC D2 is great, the G-Force is better as you get all the modulation as well. Having the ability to have different delay times in each channel gives you the chance to get the famous "circular delay" effect used by Steve Lukather and Dave Gilmour.
Just my opinion.... take it how you like
P.S I had to add an extra L to the song Run Like Helll.... as the forum puts an asterisk in place of the word hell
