You don't need a timing tape. Simply do an accurate TDC verificaton to determine the "0" line on the balancer and then use a dial-back timing light for all your timing work. As a short-cut, you can determine/verify the "0" mark with a good TDC verification and then simply measure the circumference of the balancer and divide by 10 to put a line at the 36-degree mark - this is all you'll need to work your timing issues since your timing tab will allow you to see and work within +/- 4 degrees of the 36-degree mark with ease.
The Powerforce 80020 balancer works fine, but it is not SFI-approved. It has 60 degree marks plus a mark at each 90-degree interval. For a street car, there is no issue using this balancer.
The Engine Pro products are serious racing products, but their 2 entry-level quality levels are also not SFI-approved. They do not degree their balancers, because they assume that any knowledgable engine builder will determine TDC and mark the balancer according to where he decides to put the timing pointer - this is a normal part of the engine building process. If you chose to use the Engine Pro balancer, have your engine builder mark the correct "0" point on the balancer and install the timing pointer correctly. Then, use a dial-back light for engine timing, as you should be doing anyway...
I've seen a lot of balancers come apart, including stock balancers, Pioneer, and Engine Pro. One of the key failure modes, regardless of balancer brand, has been the technique used during balancing (drilling and removing material too close to the OD of the outer ring) and bore tolerancing during installation: Many high perfrmance balancers are not slip fit like a stock Pontiac, and the engine builder must hone the bore to the correct press fit size - forcing a high performance balancer onto the crank snout without doing the correct sizing and honing will cause the balancer to fail.
