Steve,
If you can afford to bring it all back like you are talking about, then afford the tanning fees, go for it. I brought back 7 trophies last year...I'm expecting "the call" any day now from my taxidermist. I have a thread a little further down outlining what I brought back and what I paid. I brought back the capes for Kudu, Gemsbok, and Bushbuck shoulder mounts and then the full capes for wildebeest and hartebeest to make rugs from later. I euro mounted the wildebeest, hartebeest and two impala. Definately find a good taxidermist here and plan things with him before you go.
Have fun!
Toby
