I don't think you need the compression strut if you don't use the jib. Not sure you really need it with the jib honestly if you have good non stretch mid spin pole bridle lines. The HT I used to have did not have a strut there- all it had was what I called a spin pole lift line that went to the forestay then to the middle of the spin pole. I think I might set mine up without the strut one of these days.
