Setting Shipping Methods Based on Weight

[PeauProductions]

Ok so something like this?

// BOF: UPS USPS
        $this->quotes = array('id' => $this->code,
        'module' => $this->title . $show_box_weight);
        // EOF: UPS USPS

        $methods = array();
        $size = sizeof($uspsQuote);
        for ($i=0; $i<$size; $i++) {
          list($type, $cost) = each($uspsQuote[$i]);

       echo 'I SEE usps type: ' . $type . '<br>';

          // BOF: UPS USPS
          $title = ((isset($this->types[$type])) ? $this->types[$type] : $type);
          if(in_array('Display transit time', explode(', ', MODULE_SHIPPING_USPS_OPTIONS)))    $title .= $transittime[$type];
          /*
          $methods[] = array('id' => $type,
          'title' => ((isset($this->types[$type])) ? $this->types[$type] : $type),
          'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
          */

      if($usps_shipping_weight is <= 0.99){

          $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);

      } else{

      $methods[] = array('id' => $type,
                             'title' => $title,
                             'cost' => ($cost + MODULE_SHIPPING_USPS_HANDLING) * $shipping_num_boxes);
      }

        } 

But how do I specify which type to filter for?
