since you already own a multi-tip line that means you already have the tips. keep the tips from the rio line, buy a good full floating line (choose a belly length you are comfortable with), chop off 15' from the tip, put a loop on it and use your existing tips. why spend the money (or store credit) twice on a multi-tip line?

if you lost one of the tips when the line cut, just buy a replacement rio 15' tip (any decent rio dealer should carry them).
