I have not done any strict test trials on this, but I have been paying attention these last couple of years on how comb is drawn out on foundation, with housal positioning in mind, with different frame orientations in the brood nest and honeysupers. I have found there to be no difference in the success of straight drawn comb, which ever way the combs are placed in the hive. Burr comb ,miss drawn drone comb and sutch have no relation to my success in drawing comb or with the arrangement of food stores and brood nest pattern in the hive. Like I said, I have not done any formal trials on it, but this is what i conclude from my observations. The biggest factor in successfull straight drawn comb is best with a heavey honey flow, and/or heavey feeding., not to mention stronge healthy hives full of younger bees. Given those two factors, foundatin will be drawn out perfect nearly every time. I now dont waste my time thinking of housal positiioning Ian :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
