Not really. The the foreguy at the base of the mast works as described by dbows regardless of whether you have a bridle or a center D ring on your spin pole. In either case the angle is not as effective at preventing the outboard end of the pole from rising so you might want to apply more tension with a purchase.
Seems to me the extra block at the base of the mast for the topping lift is one more piece of gear for the jib sheets to catch on during a tack (as is the block for the foreguy). Couldn't you just use the usual cam cleat near the topper exit and grasp the tail aft of the existing turning block if you prefer to pull up instead of down?
