Hi cljfford,
Unfortunately, Logic and Reason look for the plug-ins in two totally different places, so install both will double the amount of space the install takes. However, as you notice, the plug-in is only about 30MB, so it's not a very big file. Normally, if you want to use the plug-in in both DAWs you'll install both plug-in formats. However, if you want to use it in Reason only, VST only is fine.
Good luck, and let us know if you have any other questions!
Thanks,
Dan
