used 2 in sask for several years. at 58 you might have some issues with position as interior calls for mostly kneeling, as a alternative we used cinder blocks (4) to get the whole bird off the ground and use a stool to sit on. Also using a call is muted. I am 56 and in my experience the low profile like you are using now are the ticket. The more comfortable the blind, makes it harder to score. Permanent pits and hedgerows are my favorite for comfort, on the Eastern Shore of Maryland in its day was a great setup. Stick with the low profile you are using and really learn to use a Goose call and take advantage of the mobility of the blind you are using now.Good calling and good shooting will add more to the bag.
